Perhaps you should try some spelling variations:
thanh tung » thanh cong
hoc thieu » toc thieu, hoc hien
ho chieu » theo chieu, doi chieu, mot chieu
tung cua » trung cua, tuong cua, dung cua
cua dung » cua dang, cua dong, qua dung
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
than cao » toan cao, thai cao, than cap

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) tinh - thanh tung cua dung ((cong dan) OR (cong tan)) than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) tinh - thanh tung cua dung ((cong dan) or (cong tan)) than cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) tinh - thanh tung cua dung ((cong dan) or (cong tan)) than cao*.
